The net economic value of reproductive efficiency in dairy cattle was estimated using a stochastic dynamic simulation model. The objective was to compare the economic consequences of reproductive performance scenarios ("average" and "poor") of a cow having a good reproductive performance and to explore which reproductive factors have an important impact on economic efficiency. A "good" reproduc...

Previous reports on the inverse association between ‘mate’ intake (infusion of Ilex Paraguariensis herb) and breast cancer (BC) risk led us to consider two main roles for the infusion: as a substantial antioxidant contributor and as a hormone regulator, particularly through anti-aromatase capacities. Since menstrual-reproductive risk factors for BC reflect women’s estrogenic exposure during the...

background & aim: men’s sexual and reproductive health is one of the most important public health issues. however, less attention has been paid to this matter, compared to women’s health issues. the aim of this study was to evaluate the educational needs of men regarding sexual and reproductive health in ahvaz, iran. methods:this descriptive study was performed on 1,068 adult men (aged 20-60 ye...

The objectives of this presentation are to review results of our previous and on-going research with respect to the risk factors and consequences of poor reproductive performance in dairy cows, and to develop an economic framework to optimize decisions related to dairy cow reproductive performance. To make profitable breeding and replacement decisions, the farmer must account for factors includ...

BACKGROUND Previous studies have shown that age at menopause is an important indicator of duration of endogenous estrogen exposure. The present study investigates whether combining more information on reproductive factors is useful in estimating individual total duration of exposure to endogenous estrogens. METHODS Bone mineral density (BMD) was used as operational outcome. The study populati...

Transcription factors in the germline play important roles in ovary formation and folliculogenesis, and control both oocyte development and somatic cell function. Factor in the germline (Figla) and newborn ovary homeobox gene (Nobox) represent a growing number of oocyte-specific transcription factors that regulate genes unique to oocytes. Studies on oocyte-specific transcription factors are imp...
